An angular-position and torque sensor assembly includes a low-hysteresis coupling for an assembly including a plurality of shafts. The coupling comprises an inner member, an outer member, and a base member disposed outside the outer member. The inner member and base member are coupled to the shafts.

An angular-position and torque sensor assembly includes a low-hysteresis coupling for an assembly including a plurality of shafts. The coupling comprises an inner member, an outer member, and a base member disposed outside the outer member. The inner member and base member are coupled to the shafts. First rails connect the inner member to the outer member, and the first rails allow the inner member to be readily displaced relative to the outer member only in a direction substantially perpendicular to a longitudinal axis of the first rails. Second rails connect the outer member to the base member, and the second rails are aligned perpendicular to the first rails. The second rails allow the outer member to be readily displaced relative to the base member only in a direction substantially perpendicular to a longitudinal axis of the second rails. Due to the connection means of the first and second rails, the inner member is free to move in an x-y direction relative to the base member in an x-y plane parallel to the surface of the base while being rotatively fixed in a z axis relative to the base member.

1. A method for accommodating axial displacement between two elongated members, comprising:coupling an inner member to an outer member with first rails; coupling a first elongated member to the inner member, the first elongated member having a first longitudinal axis; allowing the inner member and the first elongated member to be readily displaced relative to the outer member only in a direction perpendicular to a longitudinal axis of the first rails; connecting a base member to the outer member with second rails, the second rails being substantially perpendicular to the first rails; allowing the outer member to be readily displaced relative to the base member only in a direction perpendicular to a longitudinal axis of the second rails; fixedly connecting a second elongated member to the base member, the second elongated member having a second longitudinal axis, the first longitudinal axis differing from the second longitudinal axis; and allowing the first elongated member to rotate relative to the second elongated member while allowing the first elongated member to be displaced in an x-y direction along an x-y plane parallel to a surface of the base member.
