A quick change coupling arrangement for holding an actuator shaft of a hydraulic dampening unit to a valve shaft of a swing check valve. The coupling arrangement provides knob portions arranged on opposing free ends of the valve shaft and the actuator shaft, which are captured in sandwich fashion between two semi-circular cylindrical shell connectors. An outer sleeve is provided which can be temporarily displaced upward on the actuator shaft during assembly of the shell sections over the knob portions and then slid downward to cover the shell sections and hold the shell connectors together preventing radial departure from the knob portions. A set screw is provided to hold the sleeve in axial fixation with one of the shell connectors.

Dispositif à raccordement rapide pour relier l'axe d'un actionneur d'amortisseur hydraulique à une tige de soupape ou à un clapet de retenue. L'assemblage comporte des boutons montés aux extrémités libres et opposées de la tige de soupape et de l'axe de l'actionneur, lesquels sont en sandwich entre les connecteurs des enveloppes cylindriques semi-circulaires. Un manchon extérieur peut aussi être temporairement déplacé vers le haut sur l'axe de l'actionneur au cours de l'assemblage des sections cylindriques par-dessus les boutons, pour ensuite être redescendus pour couvrir les sections des cylindres et maintenir les connecteurs ensemble et prévenir la dérive radiale par rapport aux boutons. Une vis de calage est prévue pour fixer le manchon dans une direction axiale avec l'un des connecteurs de l'enveloppe.
