Abstract
A torsionally-rigid compensating coupling between first and second shaft ends has a ball bearing element positioned on the first shaft end and a ball socket element with grooves positioned on the second shaft end, with the ball bearing element including a ball bearing and a drive pin extending through the ball bearing. Pin ends of the drive pin extend out of the ball bearing into the grooves of the ball socket element. The grooves and ball socket of the ball socket element, in a longitudinal direction of the second shaft end, open out into a cylindrical recess that has a guide chamfer. The ball bearing element includes an elastic-force creating member and stops, with the elastic-force creating member driving the drive pin against the stops to fix the drive pin in its working position by elastic force, the drive pin being moveable against the elastic force in a longitudinal direction of the second shaft end.
