A device for changing the control times of gas exchange valves in an internal combustion engine including a crankshaft driven component, and a camshaft component driven by a camshaft and affixed thereto is provided. The crankshaft driven component is connected to the camshaft component for power transmission via two pressure chambers. The pressure action causes a relative rotation or hydraulic adjustment of the camshaft component relative to the crankshaft driven component. In addition, the device has an impulse generator wheel fixed to the camshaft component, for ascertaining the position of the camshaft, and a spring attached to the two components for rotating the camshaft to a preferred position for starting the internal combustion engine. The spring is arranged outside the device in a hollow space located between the impulse generator wheel and the axial side facing the wheel, and is enclosed at least on two sides by the impulse-generator wheel.
