A screw and nut linear drive assembly includes a housing, a screw within the housing, an electric motor for rotating the screw, a nut which is driven, when the screw is rotated, to move linearly in a longitudinal direction coinciding with the screw axis, and an axial force transfer arrangement to transfer force from the nut to a push rod to be connected to a member to be actuated by the assembly. The transfer arrangement includes a sequential arrangement of a first and a second axial force transferring component in force transmitting contact that are configured such that first contact points between the first and second axial force transferring components define a first axis (in a plane perpendicular to the longitudinal direction, about which the second axial force transferring component is capable of tilting with respect to the first axial force transferring component to reduce torque transfer to the nut).

A position dependent valve device () for a control cylinder () includes at least one channel () formed in one of a wall of a cylinder housing () of the control cylinder () and a wall of a internal piston () disposed in the cylinder housing () and a seal () including a flexible member adapted to be disposed in a groove in the other one of the wall of the cylinder housing () and the wall of the piston (), the seal () cooperating with the at least one channel () when the piston () is in a defined position to allow airflow past the piston () and cooperating with one of the cylinder housing () and the piston () when the piston () is in a position outside the defined position to prevent airflow past the piston ().
