A torque-sensing rotary tool for use in bottle-capping, and other such applications. The tool (10) is characterized by independent motors (30 and 40) means for gripping and rotating bottles or the like and a rotation-counter which forms means, with associated circuitry (FIG. 9), to determine when an object, e.g. a bottle cap, may be safely lifted by automatic machinery, e.g. by robot means.
