Device for connecting an angular sensor and a torsion bar

The arrangement has a flange (28) made of pressed steel and having two branches (38, 40) articulated on a base (36) to form a clamp. The branches are activated elastically towards a clamped position on a pivoting section (22) of a torsion bar (14). The flange has a clamping screw (68) tightened in a bolt (66) through the branch (40) so that the branches are tightened against flat sections (54) of the section (22) in the position.
