ABSTRACT:
A coupling is in two parts. One part is connected to the element to be driven and that part is a flat-face, circular member with three spaced grooves on its face and three spaced grooves on its circular edge. The second part is connected to the drive element and is a three jaw chuck with wedges on the jaws to engage the grooves on the circular edge of the first part. The three jaws have spring-biased projections that engage the grooves on the face of the first part to initially have the second part drive the first part.
