Abstract
The clutch element for coupling and uncoupling the coupling elements of the shaft coupling arrangement is rotatably mounted on one coupling element and is rotated by an actuating tool external to the clutch element. The tool includes a drive shaft, crank webs which extend transversely of the drive shaft and a pair of rollers which are disposed externally of the coupling elements. The clutch element includes a pair of wedges sandwiched between two circular segment plates and pivotally mounted on a projection of a push rod. The wedges engage in pockets on the exterior of the coupling elements.
