Claim 17:
18. A linear-to-rotary motion apparatus comprising:
a linear actuator comprising:
an actuator housing comprising a piston chamber; and
a piston shaft disposed at least partially within the piston chamber and configured to translate within the piston chamber along a translation axis, the piston shaft comprising a piston shaft end configured to selectively extend and retract linearly along the translation axis relative to the actuator housing; and

a rotor apparatus comprising:
a rotary joint defining a rotational axis that is substantially perpendicular to the translation axis;
a rotor arm extending radially from the rotary joint and configured to pivot about the rotary joint, the rotor arm having a first rotor arm end proximate to the rotary joint and a second rotor arm end away from the first rotor arm end; and
a torque linkage having a first torque linkage end pivotably connected to the second rotor arm end of the rotor arm, and a second torque linkage end opposite the first torque linkage end and pivotably connected to the piston shaft end of the piston shaft at a pivot connection joint, the pivot connection joint defining a pivot axis that is substantially perpendicular to the translation axis of the piston shaft, wherein the rotor arm at least partially overlaps the piston shaft in a two dimensional viewing plane and the rotor arm is separate from the linear actuator, the pivot axis and the rotational axis being normal to the two dimensional viewing plane.
