Valve controller for reciprocating piston internal combustion engines with at least two intake and/or exhaust gas-exchange valves for each piston/cylinder unit, wherein the gas-exchange valves are guided by valve stems in a cylinder head (8) of the reciprocating piston internal combustion engine, loaded in a closing direction by valve springs, and can be controlled via a common bridge (10) by an activation device, wherein the bridge (10) is guided over a sliding surface parallel to the movement of the gas-exchange valves, the bridge (10) has at least one hydraulic valve clearance compensation element (14 or 15) that connects to a gas-exchange valve, and a device is provided that prevents rotation of the bridge (10) about the sliding surface.
