Adaptor between a flange connector and a signal representation of the flange. This component is used to provide a pure signal interface around a Rotational model and export this model in form of an input/output block, especially as FMU (Functional Mock-up Unit). Examples of the usage of this adaptor are provided in Rotational.Examples.GenerationOfFMUs. This adaptor has angle, angular velocity and angular acceleration as input signals and torque as output signal. Note, the input signals must be consistent to each other (w=der(phi), a=der(w)).
