The adapter assembly (200) includes at least one drive converter assembly (240) including a drive shaft (242)； a drive coupling nut (244) threadably connected to a distal end portion of the drive shaft (242)； and an axially translatable drive bar (246) connected to the drive coupling nut (244), wherein rotation of the drive shaft (242) results in axial translation of the drive bar (246). The drive coupling nut (244) engages 29 teeth of the threaded distal end portion (242b) of the drive shaft (242). The drive coupling nut is manufactured from unreinforced PEEK thermoplastic polymer.5/9 242a 242 2I.240 2306 24FI2.55
