A torque sensor 100 comprises a shaft 125 rotatable in use to cause a rotation of an output (for example, a gear 110), wherein the shaft is axially moveable in two directions in response to thrust loads caused by the applied torque. A housing at least partially surrounds 160 the shaft. A spring pack assembly 140 is disposed on the shaft 125, the spring pack comprising: first 146 and second 147 bearings. Each bearing is disposed between the shaft 120 and the housing 160 and is axially movable relative to both the shaft and the housing. A resiliently axially compressible spring member 142 is disposed between the first and second bearing assemblies. The shaft 120 has first 122 and second 128 axial stops respectively positioned on the outside of the first 146 and second 147 bearings and arranged to limit the axial position of the bearings relative to the shaft. The housing 160 has first 162 and second 166 axial stops respectively positioned on the outside of the first 146 and second 147 bearings and arranged to limit the axial position of the bearings relative to the housing. |
