identifier needed to adress subdevices

[JB-Wolf]

Problem

when device decomposition happens, commands to the device assembly need to have an identifier to be sent to the correct device.

suggestion

since each subdevice needs a unique name anyway and this unique name is used in the config file (if I gather that correctly), the device name could also be used to generate the correct addressing information.
calling subdevice.component_info.name gives the name, which can be fed to the command which needs to be issued to the correct device.

alternative

alternatively, additionally to name, a identifier can be introduced into hardware device and used, if existing, to modify commands
