1. A no-back brake mechanism, comprising: a plurality of rollers each mounted within a respective roller cage,wherein the roller cages being articulated about an axis such that rotation of the rollers in a first direction causes no movement of the cages about their axis and rotation of the rollers in a second direction opposite the first direction causes the cages to rotate with respect to their axis. 2. The mechanism of claim 1, further comprising stop means arranged to prevent rotation of the cages relative to their axis when the rollers rotate in the first direction. 3. The mechanism of claim 2, wherein the stop means is adjustable. 4. The mechanism of claim 1, further comprising angle stop means arranged to stop rotation of the cages beyond a selected angular position when the rollers rotate in the second direction. 5. The mechanism of claim 4, wherein the angle stop means is adjustable. 6. The mechanism of claim 1, wherein the plurality of rollers is arranged in a ring configuration defined by the axis of rotation of the roller cages. 7. The mechanism of claim 6, wherein the axes of rotation of the roller cages are located on a plate of an input shaft. 8. The mechanism of claim 6, further comprising: a rotating plate arranged within the ring defined by the axes and in surface contact with the rollers such that rotation of the rollers causes a corresponding rotation of the rotating plate. 9. The mechanism of claim 8, further including: a roller functioning as a thrust bearing in surface contact with the rotating plate, the rotating plate positioned between the rollers and the thrust bearing, such that rotation of the rollers causes rotation of the rotating plate which, in turn, causes rotation of the thrust bearing. 10. The mechanism of claim 1, mounted in a housing and arranged to cooperate with a rotating system. 11. A no-back brake mechanism, comprising: a plurality of rollers each mounted within a respective roller cage, wherein the roller cages being articulated about an axis such that rotation of the rollers in a first direction provides a first amount of friction and rotation of the rollers in a second, opposite, direction provides a second, greater amount of friction. 12. An actuator system comprising a rotating system comprises: a rotating shaft about which is mounted a rotating shaft plate; anda no-back mechanism, the no-back mechanism including: a plurality of rollers each mounted within a respective roller cage, wherein the roller cages being articulated about an axis such that rotation of the rollers in a first direction causes no movement of the cages about their axis and rotation of the rollers in a second direction opposite the first direction causes the cages to rotate with respect to their axis;wherein the rotating plate is in surface contact with the rollers such that rotation of the shaft in the first direction causes corresponding rotation of the plate which induces rotation of the rollers in the first direction, and rotation of the shaft in the second direction causes corresponding rotation of the plate which induces rotation of the rollers in the second direction. 13. A torque limiter mechanism, comprising: a plurality of rollers each mounted within a respective roller cage,wherein the roller cages being articulated about an axis such that rotation of the rollers in a first direction causes no movement of the cages about their axis and rotation of the rollers in a second direction opposite the first direction causes the cages to rotate with respect to their axis. 14. The mechanism of claim 13, further comprising stop means arranged to prevent rotation of the cages relative to their axis when the rollers rotate in the first direction. 15. The mechanism of claim 14, wherein the stop means is adjustable. 16. The mechanism of claim 13, further comprising angle stop means arranged to stop rotation of the cages beyond a selected angular position when the rollers rotate in the second direction. 17. The mechanism of claim 16, wherein the angle stop means is adjustable. 18. The mechanism of claim 13, wherein the plurality of rollers is arranged in a ring configuration defined by the axis of rotation of the roller cages. 19. The mechanism of claim 18, wherein the axes of rotation of the roller cages are located on a plate of an input shaft. 20. The mechanism of claim 18, further comprising a rotating plate arranged within the ring defined by the axes and in surface contact with the rollers such that rotation of the rollers causes a corresponding rotation of the rotating plate.
