L'adaptateur est conçu pour relier l'actionneur rotatif à l'extrémité d'entrée afin d'entraîner la rotation du dispositif d'entraînement rotatif. L'extrémité de sortie est configurée pour être reliée au mécanisme d'ouverture de soupape de façon à entraîner la rotation du mécanisme d'ouverture de soupape pour déplacer la soupape d'une position ouverte ou fermée à l'autre de la position ouverte ou fermée. L'adaptateur comprend également un ou les deux parmi : un frein (38), dans lequel, lorsque le frein se trouve dans un premier état de non-freinage, l'extrémité de sortie du dispositif d'entraînement rotatif est libre de tourner et, lorsque le frein se trouve dans un second état de freinage, l'extrémité de sortie du dispositif d'entraînement rotatif ne peut pas tourner ; et un embrayage (28) configuré pour désengager l'extrémité d'entrée de l'extrémité de sortie.
