The invention concerns a device for coupling the torque transmission between a primary shaft and a receiving shaft to enable an angular and/or radial misalignment and/or an axial displacement between the two shafts, comprising two hubs (2) each provided with an external toothing (3) normally symmetrically convex with respect to a symmetrical plane (4) and a sleeve tube (7) having an internal toothing (8) co-operating with each external toothing (3) and capable of sliding longitudinally on them, limit stop means (9) being arranged in a ring-shaped space (10) between a wall (11) bearing the external toothing (3) and part (12) of at least of one of the hubs (2) and comprising a ring-shaped stop (15) fixed to the hub (2) in the symmetrical plane (4) and, at least on one side of the stop (15), a stop pin (16, 17) associated with the stop (15), arranged in the shape of a ring of the same diameter as that of the stop (15), perpendicular to the axis (18) of the sleeve tube (7), and fixed to it.

Accouplement de transmission d'un couple de rotation entre un arbre moteur et un arbre récepteur, agencé pour permettre un désalignement angulaire et/ou radial et/ou un déplacement axial entre les deux arbres, comprenant deux moyeux (2) qui sont munis chacun d'une denture externe (3) bombée usuellement symétriquement par rapport à un plan de symétrie (4) et un manchon (7) qui présente une denture interne (8) coopérant avec chaque denture externe (3) et qui peut coulisser longitudinalement sur ces dernières, des moyens de butée (9) étant agencés dans un espace annulaire (10) entre une paroi (11) portant la denture externe (3) et une partie ( 12) d'au moins un des moyeux (2) et comportant une butée annulaire (15) qui est fixée au moyeu (2), à l'endroit du plan de symétrie (4) et, au moins d'un côté de la butée (15), un arrêt (16, 17) associé à la butée (15), qui est disposé en forme d'un anneau d'un diamètre semblable à celui de la butée (15), perpendiculairement à l'axe (18) du manchon (7), et qui est fixé à ce dernier.
