Abstract: A coupling device includes two coaxial shafts, namely a tubular outer shaft and an inner shaft, capable of rotating about a reference axis; a wrap-around raceway formed on a first one of the coaxial shafts; an oblique raceway formed on the second coaxial shaft and a play take-up rail provided with a complementary raceway and movable relative to the second coaxial shaft parallel to a plane perpendicular to the reference axis. A row of balls is positioned to run parallel to the reference axis on the wrap-around raceway, the oblique raceway and the complementary raceway, to guide the two coaxial shafts relative to each other in translation.

Abstract: In order to provide a fail-safe operating mode during a transition between an autonomous steering mode and a driver-controlled steering mode in an emergency situation, a steering system comprises a steering shaft, a brake mechanism movable between an released position and a engaged position for angularly locking the steering shaft, and an override such that a non-destructive external torque applied to the steering shaft above a given threshold when the brake mechanism is in the engaged position results in a rotation of the steering shaft.
