Abstract
A rotary position sensor senses rotation of a first member, having a first torque coupling surface, about an axis relative to a second member by sensing movement of a torque receiving component of the rotary. The isolator may include a mount, a linkage and a torsion spring. The linkage is to be coupled to the torque receiving component of the rotary sensor. The linkage has a second torque coupling surface separable from the first torque coupling surface by a play gap, wherein during rotation of the first member, the first torque coupling surface is to contact the second torque coupling surface to transmit torque to the linkage. The torsion spring is captured between the mount and the linkage independent of the torque receiving component to resiliently bias the second torque coupling surface through the play gap and into engagement with the first torque coupling surface.
