Abstract

In the case of a known screwing device which is provided with means for electric signal transmission to a vibration body, disturbances to the torque measuring signal may occur, which situation is to be avoided. The screwing device has an electrical signal transmission element (21) which serves for the electric activation of a vibration body (19) arranged on a screw (14) and for torque measuring-signal transmission to a control circuit (17). The circuit is closed via an earth conductor (25) which is of a hollow-cylindrical design and encloses the transmission element (21). The earth conductor (25) makes contact with the screw head at a distance from the vibration body (19). The transmission element (21) and the earth conductor (25) can be displaced axially counter to spring force, with the result that, during screwing-in, they rest with prestressing against the vibration body (19) and the screw head (16). <IMAGE>
