Abstract
A device for detecting torque features of an electric screwer comprises a clutch for coupling with the electric screwer and a clutch for applying a resisting torque. The two clutches () are connected to one another by a shaft () on which there are arranged extensometers () for measuring the torque transmitted by the shaft. On the shaft there is splined a disc () that bears on at least one face circular tracks () that are coaxial to the shaft and to which the extensometers are electrically connected. Sliding contacts () rest elastically on said circular tracks in a direction that is substantially parallel to the axis of the shaft to pick up the electric signals from the extensometers. An encoder () is provided to detect shaft rotation.
