Introduction
A coupling is one of the most common parts of machines because it is so 
important in systems that move power from one place to another. So, they 
can be used in a lot of different applications and service settings.
Because of this, over the years, designers and engineers have made many 
different kinds of couplings for different service conditions and 
environments.
In this, you will learn about the different kinds of couplings and how to 
choose the best one for your needs.
Coupling
Coupling refers to the connection or linking 
of two or more components or systems to 
achieve a specific function.
Coupling is an essential mechanism for 
transmitting power and torque between 
shafts, gears, pulleys, and other mechanical 
components.
Coupling
There are various types of couplings available, such as rigid couplings, 
flexible couplings, fluid couplings, magnetic couplings, and gear couplings. 
Each type of coupling has its unique features and advantages, and the 
choice of coupling depends on the specific mechanical function and the 
requirements of the system.
Miller couplings are frequently used in the building, repairing roads, and 
general irrigation sectors for the pumping and transmission of water. 
Coupling is a fundamental concept in mechanical engineering, and it plays a 
critical role in the design, operation, and maintenance of mechanical 
systems.
