There is provided herein a device (30A) for selectively transmitting torque between an input shaft (32A) and an output shaft (34A), including: a first plurality of friction disks (36A) configured to rotate with the input shaft (32A); a second plurality of friction disks (38A) configured to rotate with the output shaft (34A) and interdigitated with the first plurality of friction disks (36A); a plurality of roller disks (40A) wherein each of the plurality of roller disks (40A) includes a first disk-to-roller interface (44A) with one of the first plurality of friction disks (36A) and a second disk-to-roller interface (44A) with one of the second plurality of friction disks (38A); a first resilient member (50A) configured to provide a force (FspR) through the first and second plurality of friction disks (38A, 36A) and roller disks (40A); a solenoid (56A) configured to overcome the force (FspR) from the resilient member (50A) when energised. the device (30A) may be selectively placed in one of a first mode and a second mode. In the first mode only a low torque is transmittible through the device and in the second mode a higher torque is transmittable through the device (30A). An assembly, aircraft and methods are also provided.
