A tubing hanger (1) landing in a tubular element (101), having a coupling assembly (11) for hydraulic coupling between the tubing hanger (1) and the element. A coupling element (17) moves radially between an outer coupled position and an inner non-coupled position. An actuation element (25) with a contact surface (25f) exerts an outward actuation force onto an inner actuation surface (17a) of the coupling element. The actuation element comprises two actuation sections (25x, 25y) exposed to a outward force from an actuation arrangement (27). The contact surface (25f) has a distance the actuation sections. The actuation element moves in the radial outward direction so that the movement of at least one of the two actuation sections (25x, 25y) stops after the radial movement of the contact surface (25f) stops. The contact surface (25f) movement halts as the coupling element (17) reaches the coupled position. |
