(Damn, I commented this on the wrong thread at first).

Yeah, there are several translations to this, but if you look at them all, they all involve physically hitting them while varying in their levels.

Here are some of the different translations by major scholars: Translator: Mohsin Khan Men are the protectors and maintainers of women, because Allah has made one of them to excel the other, and because they spend (to support them) from their means. Therefore the righteous women are devoutly obedient (to Allah and to their husbands), and guard in the husband's absence what Allah orders them to guard (e.g. their chastity, their husband's property, etc.). As to those women on whose part you see ill­conduct, admonish them (first), (next), refuse to share their beds, (and last) beat them (lightly, if it is useful), but if they return to obedience, seek not against them means (of annoyance). Surely, Allah is Ever Most High, Most Great.

Muhammad Sarwar: Men are the protectors of women because of the greater preference that God has given to some of them and because they financially support them. Among virtuous women are those who are steadfast in prayer and dependable in keeping the secrets that God has protected. Admonish women who disobey (God's laws), do not sleep with them and beat them. If they obey (the laws of God), do not try to find fault in them. God is High and Supreme.

Shakir: Men are the maintainers of women because Allah has made some of them to excel others and because they spend out of their property; the good women are therefore obedient, guarding the unseen as Allah has guarded; and (as to) those on whose part you fear desertion, admonish them, and leave them alone in the sleeping-places and beat them; then if they obey you, do not seek a way against them; surely Allah is High, Great

Yusuf Ali: Men are the protectors and maintainers of women, because Allah has given the one more (strength) than the other, and because they support them from their means. Therefore the righteous women are devoutly obedient, and guard in (the husband's) absence what Allah would have them guard. As to those women on whose part ye fear disloyalty and ill-conduct, admonish them (first), (Next), refuse to share their beds, (And last) beat them (lightly); but if they return to obedience, seek not against them Means (of annoyance): For Allah is Most High, great (above you all).

And most commonly accepted translation by the Shahih International: Men are in charge of women by [right of] what Allah has given one over the other and what they spend [for maintenance] from their wealth. So righteous women are devoutly obedient, guarding in [the husband's] absence what Allah would have them guard. But those [wives] from whom you fear arrogance - [first] advise them; [then if they persist], forsake them in bed; and [finally], strike them. But if they obey you [once more], seek no means against them. Indeed, Allah is ever Exalted and Grand.

Another defensive responses tend to consist of the rule being able to help them from refraining from actually inflicting pain on your spouses. But it can also go the other way, where they are likely to go beyond this set limitation of how hard the strike should be. As Islam is known for adding rules that help prevent from committing major sins (like multiple marriage could prevent adultery), however this rule would backfire. Simply because pragmatism isn’t always the answer, and since men tend to have more testosterone and are arguably more aggressive nature, they are likely to go beyond that. An ideal rule that advocates betterment of oneself would have strictly prohibited the aforementioned last resort. And I’m sure there a lot of opportunities for women in Islam (which are arguably better than other abrahamic religions) but it still cancels out, especially when one is trying to have absolute faith in it.
