A torsionally tuned damper assembly for a geared power transmission is disclosed. The carrier has a first and second bearing surface, the first bearing surface of the carrier having multiple antenna units placed on it separately, so that the loading structure of the antenna units goes through the first bearing surface to the second bearing surface. Each respective joining structure of the plurality of joining structures maintains the adjoining members oriented substantially about a respective axis. The elongate locking handle can be rotated over the lance to prevent movement of the lance during the container filling procedure.
