Abstract
A shaft coupling for connecting two shaft ends to transmit torque. Each shaft end has a recess or a projection. A projection on one shaft end projects into the recess in the other shaft end and their cooperating side walls transmit torque. A centering device at one shaft end cooperates with a centering device on the other shaft end for axially aligning the shaft ends. These may be a cylindrical projection one shaft end and a corresponding recess in the other shaft end. Alternatively, the centering devices are recesses in both shaft ends and a pin that extends into both of the centering recesses. Applied elastic material on at least one of the centering device elements enables secure attachment between the shaft ends.
