A power tool including: a motor; a shaft for delivering a torque to a joint or the like, the shaft being drivingly connected to the motor; and a housing that at least partly houses the motor and the shaft. The shaft includes a longitudinal cavity in which a torque transducer is arranged to measure a torque acting over a portion of the shaft, wherein the longitudinal cavity includes: a first contact surface for torque transferring contact with a first end portion of the torque transducer; and a second contact surface, separated from the first contact surface, for torque transferring contact with a second end portion of the torque transducer, the portion over which the torque is measured being located between the first and second contact surfaces. |
