A universal coupling primarily intended for connecting a pair of noncoaxial shafts; that is, shafts which are angularly related or misaligned, the coupling including a pair of ball members mounted on the shafts and journaling encompassing structures having interior portions conforming to the ball members, the structures being rigidly connected by bars or incorporating gears, or connected sheaves or sprockets which tend to maintain the encompassing structures in coplanar relation, the structures being connected to the ball members by diametrically disposed key slot and pivotal key elements to effect a drive connection between the shafts.
