INVENTOR: KLAUS ARNDT INVENTION: ARRANGEMENT FOR THE RIGID CONNECTION OF A DRIVEN SHAFT WITH A GRADUATED DISK OF A PRECISION MEASURING INSTRUMENT ABSTRACT OF THE DISCLOSURE An arrangement for the rigid connection of a drive or driven shaft with a coding disk of an angle coding device. Arranged at the drive shaft is a one-piece compensation ring comprising a first flange for receiving and attachment of a coding disk, a second flange for securing such compensation ring to the drive shaft, and a sleeve element interconnecting the two flanges. The first flange and the sleeve element are divided into segment portions or segments by slits distributed on the periphery, whereby there are absorbed most of the radially acting forces which are caused mainly by the different coefficients of expansion of the relevant materials. The arrangement is particularly suitable for a coding disk which is rigidly connected for rotation to the drive or driven shaft and which is operatively associated with an angle coding device for the reading of the elevation or azimuth alignment movement of an observation periscope.
