Match adapter to controller based on module rather than key

[GDYendell]

This method matches adapters based on the "index" the adapter is loaded as, which requires the deployments be configured with that exact name. The API exposes the name of the class of the adapter, which is static (unless the source code is changed), so would be much more reliable.

e.g. response = {..., 'module': {'value': 'EigerFanAdapter', 'writeable': False, 'type': 'str'}, ...}

Update _create_adapter_controller to read this status and match on the class name instead of the arbitrary index name. The initialise method should probably extract this and pass the class name into _create_adapter_controller, as it has already done a request of the full tree here so has that available.
