"How to select the appropriate coupling for a specific application?"

Selecting the right coupling depends on several factors. The torque requirements of the application are crucial; the coupling must be capable of transmitting the required torque without failure. The amount of misalignment that may occur between the shafts needs to be considered. If there is significant misalignment, a coupling with higher flexibility is needed. The operating speed also influences the choice; some couplings are better suited for high-speed operations. The environmental conditions, such as temperature, humidity, and the presence of corrosive substances, also play a role. Additionally, the cost and maintenance requirements should be taken into account. For example, in a high-temperature environment, a coupling made of heat-resistant materials would be appropriate.
