1. An asymmetric torque limiter having an axis of rotation (A) comprising:
a first annular friction disk;
a second annular friction disk concentrically arranged with the first annular friction disk;
a skewed roller disk in contact with the second annular friction disk, wherein the skewed roller disk includes a plurality of skewed rollers mounted in an annular retainer, wherein the plurality of skewed rollers are each rotatable about a respective roller axis, each roller axis being skewed with respect to a radial direction passing through the skewed roller from the axis of rotation (A);
a first resilient member attached to the first annular friction disk and configured to bias the first annular friction disk toward an input shaft; and
a second resilient member configured to bias the skewed roller disk toward the second annular friction disk.
