Abstract
A device for coupling a shaft and the hub of a machine element such as a pulley or gear for joint rotation, includes annular outer and inner wedges each of which has angularly spaced longitudinal slots, and ribs aligned with the slots. The wedges telescope so that the ribs of one wedge extend into the slots of the other, aligning longitudinal bores of the ribs to receive fastening elements such as screws. The fastening elements thus impart relative axial movement to the wedges to expand the same radially into gripping engagement with the shaft and hub.
