Abstract: A pneumatic power tool drive mechanism having coaxial drive and driven rotors and an intermediate torsion spring and relatively rotatable in accordance with the transmitted torque. A torque indicating device of the power tool comprises an axially reciprocable and non-rotatable torque scale operator actuated in one axial direction in accordance with the relative angular displacement of the drive and driven rotors to indicate the applied torque and urged in the opposite axial direction to reset the torque scale operator through the engagement of dimples on the torque scale operator with a helical cam on the driven rotor.
