ABSTRACT:
In an angle step indicator, a positive connection for adjustment is provided between the input shaft of the angle step indicator and the drive shaft whose angular position is to be measured. The positive connection is created by a shaft end with an adjustable diameter. Preferably, the shaft end is spreadable by means of a spreading pin to generate the positive connection, whereby the spreading pin is accessible from its rear even when the angle step indicator is installed. An elastic angularly fixed connecting element takes up alignment tolerances between the input shaft and the drive shaft.
