Abstract
A torque wrench is presented which has dual output/reaction modes, with the input and output operating in the same direction in both modes. In one mode, a stationary reaction adapter is outside of an inner rotating torque adapter; in the second mode, a stationary reaction adapter is inside of an outer rotation torque adapter. Torque levels are measured by strain gages mounted on a single reaction arm and are read out digitally.
