Abstract:
1. A torque sensor that senses a torsion force applied to a shaft, comprising: a torque element connected to at least a portion of the shaft, wherein the torque element generates a torque response in response to the torsion force applied to the shaft; a response detector in communication with the torque element, wherein the response detector senses the torque response and generates an output responsive to the torque response; and a coupler attached to the shaft and the torque element, wherein the coupler transfers a portion of the torsion force applied to the shaft to the torque element, wherein the coupler comprises a first inner ring coupled to the shaft, a first outer ring coupled to the torque element; and a plurality of spokes that extend axially between the first inner ring and the first outer ring for connecting the inner ring and the outer ring, and a second inner ring and a second outer ring wherein the second inner ring is connected to the first outer ring and the second outer ring is connected to first the inner ring via said plurality of spokes.
