摘要：In a screwdriver/wrench for defined tightening of screw connections in which a screwing tool (24) is driven by a drive (16) seated in a housing (10), a torque sensor (34) for measuring the torque exerted on the screwing tool (24) is used, said torque sensor responding to the moment of reaction acting between the housing (10) and a holding flange (14) via a tubular connecting piece (12). The torque is thus measured using a stationary part. Measurement can be effected using strain gauges (36) mounted on the connecting piece (12) of small diameter. <IMAGE>
