Abstract
An assisted steering device for a vehicle has a steering column in two parts which are capable of limited relative angular play, permitting angular offsetting of the parts under the effect of the steering wheel. This enables two rotor discs, movable respectively with the two parts, to be offset relative to each other. These discs are located between two stators formed with annular grooves, and one of the discs has a circular series of passages which extend over a mean radius the value of which is between the values of the mean radii of two circular series of passages provided in the other disc.
