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.

A shaft coupling for connecting two shafts for transmitting torque comprising:
- a first shaft having an end with an axial projection;
- a second shaft having an end with an axial recess;
- the projection and the recess cooperating for transmitting torque;
- a first centering device on the end of said first shaft and a cooperating mating second centering device on the end of said second shaft, the first and second centering devices cooperating for aligning the shafts, wherein one of the first and second centering devices comprises an axially projecting centering projection and the other of the first and second centering devices comprises a centering recess for accommodating the centering projection;
- and
- an elastic material applied and rigidly connected to at least one of the first and second centering devices of a size and nature which holds the first and second centering devices and the respective shaft ends securely engaged and aligned.
