A rotary union / rotary joint is a mechanism used to transfer liquids and/or gases while rotating or swiveling from one connection to another. Rotary unions are engineered to endure a large range of temperature and pressure for a variety of conditions and environments. In addition, rotary unions may integrate multiple ports and handle different types of media concurrently.
Rotary unions function by connecting to an input and securing onto another mechanism while allowing a moving connection to be preserved. They are utilized in a variety of applications; from miniature rotary unions for the semiconductor industry to large, heavy-duty rotary unions for industrial applications. Additionally, numerous materials, seals, and bearing types can be incorporated.

That refers to something that moves around in a circle.
Unfortunately, the answer to that question is difficult to come by without knowing the location and use of the rotary couplings. The answer could be anywhere from $200-$2000. Please specify use for rotary couplings.
A rack and pinion, cam, crank, and screw can do that.

It's generally better to just buy a rotary phase converter, as they are very complex.
A rotary union is a mechanism or device that used to transfer fluid from a relatively stationary unit to a rotating outlet. They are engineered to endure a large range of temperatures and pressure.
The Rotary Union can preform a wide variety of services, and one of them is to provide a seal to a tube and a rotating piece. Another is to allow the flowing of liquids in and out of the rotating part.

A rotary system can be used to calibrate flowmeters. Unless you are refering to a rotary telephone system, in which that works differently.
Rotary Broaching is a method of producing both internal and external forms fast and accurately on the end of a workpiece. Rotary broaching makes it possible to very accurate forms within 0.0005 inches within seconds. With rotary broaching not only can you produce standard shapes such as hexagons and squares but also shapes such as Double Hex Rotary Broaches, 6-Lobe Rotary Broaches, Serration Rotary Broaches, J500 Rotary Broaches, Spline Rotary Broaches, Involute Rotary Broaches, Torx Rotary Broaches, Double D Rotary Broaches and any other Special Design Required. Rotary broaches can be made to just about any size, English or Metric. Some of the material that can be rotary broached is brass, aluminum and steel and can go as much as 2 inches deep.
