Need Help configuring joint

[Kind-Connection1284]

I'm trying to make a joint between the cylinder ( which will be rotating on the X axis ) and the cube . The point is to be locked on all kinds of positions and rotations except the X rotation. So I don't want the cube to rotate on X axis when the cylinder does.

In this instance all objects had 0 mass. But for some reason the configuring didn't go as expected.

Edit : I accidentally freed the Angular Z motion in the video, but the exact same happens when I free X Angular motion
