Zusammenfassung:The screwing tool has a drive shaft which can be coupled to a reduction gear with interposition of a coupling device. The coupling device has two coupling parts to be brought into engagement with one another. For engaging the displaceable coupling part, provision is made for an electromagnet whose magnetic field displaces the coupling part into its engaged position. To install the electromagnet, an elaborate housing design of the screwing tool is not necessary, so that manufacture and assembly can be simplified. The coupling device is reliably engaged and disengaged even at high shift frequencies.
