An actuator arrangement for a clutch of a drive train for motor vehicles. The coder is arranged to code the symbols using a code matrix, which can be expressed as a sum of 2K elements, in which each element is a product of a symbol or symbol complex conjugate to be transmitted and a N\xd7N representation matrix of a complexified anti-commutator algebra, extended by a unit element, and in which each matrix is used at most once in the formation of the code matrix. A limit value for the electrical drive current is determined on the basis of a desired speed andor on the basis of a desired acceleration with which the electric motor or the coordinate measuring device is intended to move. The software program also receives a URL address of a Web page on the Internet to be searched.
