The screwing device is assembled from a plurality of separate functional units 10, (37, Fig 1b) which can be releasably connected to one another via torque transmission coupling means 35. One functional unit 10 has axial signal transmission means 21, 22 with a rotary drive shaft 11 for transmitting electrical signals to an from a vibration body 19 on a screw 16. A second functional unit (37) has radial signal transmission means (43, 45, 46) through a wall of the rotary drive shaft to a control circuit (38). The signal tranmission between the functional units takes place via a connector 34. <IMAGE> |
