1. A position-torque sensor system comprising:
two angle sensors, wherein each of the two angle sensors is configured to detect a rotational movement and each of the two angle sensors is aligned on an axis of the rotational movement, wherein each of the two angle sensors comprises:
a rotor rotatable in response to the rotational movement to provide a rotor rotational movement; and
a stator that comprises an excitation coil and a set of receiving coils, wherein:
the rotor is rotatable relative to the stator,
the set of receiving coils generate output signals indicative of the rotor rotational movement, wherein the output signals are based on an inductive coupling of the excitation coil and the set of receiving coils, and wherein the inductive coupling traverses an axial distance in parallel with the axis, and
the sets of receiving coils of the stators of the two angle sensors are structurally the same and the rotors of the two angle sensors are structurally the same.
