Abstract (en)

[origin: EP0990489A2] The screw driver includes first entrainment elements (42) on a drive wheel (40) interacting with the second entrainment elements (47) on the cam ring (45) for force-locking transfer. A setting device (20) allows axial displacement of the tool drive shaft so that in a first position the two entrainment elements are positively locked and in a second position they disengage whilst the coupling elements (41, 46) provided on the drive wheel and cam ring come into engagement. The coupling elements and entrainment elements can be mounted on facing sides of the drive wheel
