Abstract
A coupling for transmitting a rotary motion in both directions of rotation. The coupling includes a drive shaft and a driven shaft and has a freewheeling capability in both directions of rotation for rotary motions introduced into the driven shaft. One or more balls are guided in a circular groove having an asymmetrical cross-section. The balls rest against a clamping disk having a non-circular cross-section. When the drive shaft is rotated, the balls are pressed against and clamped by a guide surface of the driven shaft.
