The invention relates to a camshaft adjuster ( 1 ) for adjusting and fixing the relative position of the angle of rotation of a camshaft ( 8 ) in relation to a crankshaft of a reciprocating piston internal combustion engine. The adjusting device comprises a high transmission and friction-reduced adjusting gear mechanism ( 2 ), comprising a drive shaft which is rotationally fixed to the crankshaft, a driven shaft which is rotationally fixed to the camshaft ( 8 ) and an adjusting shaft ( 9 ) which is connected to an adjusting motor shaft ( 10 ) of an adjusting motor. A camshaft adjuster ( 1 ), which is economical to run, can be produced such that the adjusting gear mechanism ( 2 ) and the adjusting motor ( 3 ) are embodied as separate units and are connected together by a rotational backlash-free, disengaging coupling ( 4 ).
