The device, inserted between a motor ( ) and a load ( ), allows the load ( ) to be immobilized when power is not applied to the motor ( ) and allows mechanical torque to be transmitted when power is applied to the motor ( ). Such a device is produced by virtue of a juxtaposition of brake disks rotatably connected alternately to the drive shaft ( ) and to a casing ( ) containing the motor ( ) by sliding connections, the end disks ( ) of the juxtaposition being rotatably connected on the drive shaft ( ) and by virtue of means ( ) collaborating to separate these disks and transmit the mechanical torque. The architecture of the device allows the string of dimensions associated with the functional clearance between the means ( ) to be reduced and allows the force exerted by the spring ( ) on the disk ( ) to be reacted by the bearing.
