A valve device includes a valve, a drive device, and a transmission unit. A valve changes a flow mode of refrigerant that flows in a circulation path of a refrigeration cycle device. The transmission unit includes a driving-side rotary body, a magnetic transmission member, and a driven-side rotary body. The driving-side rotary body includes multiple magnetic magnet poles in a rotational direction. The magnetic transmission member includes multiple magnetic transmission bodies which are configured to be magnetized by the magnetic magnet poles. The driven-side rotary body includes multiple magnetic magnet poles in a rotational direction. The driven-side rotary body rotates in response to a rotary motion of the multiple magnetic magnet poles of the driving-side rotary body via the magnetic transmission body. The number of the magnetic magnet poles and the number of the magnetic transmission bodies are different from each other. The rotation is transmitted from the driving-side rotary body to the driven-side rotary body via the magnetic transmission member in a non-contact manner.

A homing mechanism within a drive mechanism of a lacing engine for an automated footwear platform can include an indexing wheel, a plurality of Geneva teeth and a stop tooth. The plurality of Geneva teeth can be distributed around a portion of a perimeter of the indexing wheel. Each Geneva tooth of the plurality of Geneva teeth can include side profiles conforming to a first side profile that generates a first force when engaged by an index tooth on a portion of the drive mechanism. The stop tooth can be located along the perimeter of the indexing wheel between two Geneva teeth. Additionally, the stop tooth can include side profiles conforming to a second side profile that generates a second force when engaged by the index tooth.
