The top 5 technologies that underpin Digital Transformation for industry are as follows:
IoT Sensors and actuators

Hyper connectivity, example 5G
I think that Digital Transformation for Industry is where enterprises leverage "Internet-enabled" technologies to transform their business, processes and operations. In other words, these technologies not only underpin Digital Transformation (DX) but also enable them. The list of technologies should also include Distributed Ledger, Autonomous Robotics, Human-Machine Interfaces, and many others.
