1. A device for coupling an input shaft and an output shaft, comprising:
- a carrier coupled to the input shaft;
a pressure chamber; and
a rotary pump coupled to said carrier and the output shaft and adapted to increase pressure in said pressure chamber upon relative rotational movement of said carrier and the output shaft and to resist relative rotational movement of said carrier and the output shaft upon the presence of sufficient pressure in said pressure chamber.

Abstract
A device for coupling an input shaft and an output shaft is provided. The device includes a carrier coupled to the input shaft, a pressure chamber, and a rotary pump coupled to the carrier in the output shaft. The rotary pump is adapted to increase pressure in the pressure chamber upon relative rotational movement of the carrier and the output shaft and to resist relative rotational movement of the carrier in the output shaft upon the presence of sufficient pressure in the pressure chamber.
