The invention relates to a shaft coupling device (300) comprising: - rolling elements (310) to be engaged in grooves provided in shafts to be coupled; and - a holding base (320) enabling the rolling elements to be held in position in the grooves. According to the invention, the holding base comprises a joining portion from which a plurality of parallel arms extend, wherein each of the parallel arms bears at least one means for retaining one of the rolling elements. L'invention concerne un dispositif de couplage (300) d'arbres comportant : - des éléments roulants (310) à engager dans des rainures qui sont prévues dans des arbres à coupler, et - un socle de maintien (320) permettant de maintenir en position les éléments roulants dans les rainures. Selon l'invention, le socle de maintien comporte une partie de jonction à partir de laquelle s'étendent plusieurs bras parallèles qui portent chacun au moins un moyen de retenu d'un des éléments roulants.
