Claim 13:
14. An actuator comprising:
a motor;
a shaft mounted to the motor for rotation under control of the motor;
an actuator body comprising a first anchor body and a second anchor body;
a first tension element mounted to encircle the shaft, the first tension element comprising a first end and a second end, wherein the second end is opposite the first end, wherein the first end of the first tension element is mounted to the first anchor body of the actuator body;
a cable tensioner mounted to the second anchor body of the actuator body, the cable tensioner comprising:
a tension adjuster comprising:
a compound screw comprising:
an external shaft;
an internal shaft;
an interior aperture surface that extends lengthwise through an interior of the external shaft;
a first external thread mounted to at least a portion of an exterior of the external shaft to extend outward from the external shaft;
a first internal thread mounted to at least a portion of the interior aperture surface to extend inward away from the interior aperture surface; and
a second external thread mounted to an exterior of the internal shaft to extend outward from the internal shaft, wherein the first internal thread is mated with the second external thread; and

a spring nut comprising:
a flange;
a nut body mounted to a first face of the flange to extend outward from the first face of the flange;
a nut interior aperture surface that extends lengthwise through an interior of the flange and an interior of the nut body; and
a second internal thread mounted to the nut interior aperture surface to extend inward away from the nut interior aperture surface, wherein the second internal thread is mated with the first external thread;

a second tension element mounted to the tension adjuster, the second tension element comprising a third end and a fourth end, wherein the fourth end is opposite the third end; and
a tension element terminator, wherein the second end of the first tension element is mounted to the tension element terminator; and

a tension gauge mounted adjacent the tension adjuster to indicate a tension of the first tension element.
