Il est prévu au moins une interface client (2) qui accouple le dispositif de commande (30) au levier à détecter et émet le signal de sortie de l'unité capteur (20) et/ou positionne et/ou fixe le transmetteur d'angle (1). Selon l'invention, la géométrie de la ou des interfaces client (2) est configurée sous une forme variable au moyen d'éléments de construction séparés, et, pour la constitution de la ou des interfaces client (2), il est possible de combiner sélectivement au moins deux éléments de construction à géométrie variable à un élément de construction ayant la même géométrie.
