Abstract

The invention relates to an adjusting device (1), in particular for adjusting a camshaft, comprising a driveshaft (2), an output shaft (3), and a harmonic drive (4) which is connected between the driveshaft (2) and the output shaft (3) and which comprises a harmonic generator (7), an elastically deformable element (9), and a ring gear (10), wherein an element-side outer toothing engages with a ring gear-side inner toothing. The elastically deformable element (9) is mounted in a non-rotatable manner, and the ring gear (10) is motion-coupled to the output shaft (3).
